Title: Improvements in machines for cutting and wrapping tablets from a string of toffee orlike material
IPC: A23G7/00
Filed: 1953-07-17
Abstract: 740,260. Cutting strings of confectionery. FORGROVE MACHINERY CO., Ltd., and BROOK, L. May 27, 1954 [July 17, 1953], No. 19873/53. Class 87 (2). A machine for conveying to a transfer station a string of tablets of confectionery 11 connected to one another by thin webs of stock and resting in pockets in a conveyer chain 10 with the webs supported by knife edges 12 comprises a cutter member 14 above the chain arranged to rotate continuously about a horizontal axis disposed obliquely to the direction of travel of the chain and carrying at least one freely rotatable cutter blade 21 arranged to coact with the knife edges to sever the webs of stock in succession, each cutter blade being presented at right angles to the direction of travel of the chain on passage over the centre line thereof. The mechanism is designed to enable the connecting webs to be cut while the chain 10 moves continuously. The cutter member 14 is driven from a shaft 20 through chain drive and skew gearing. With two blades 21 the member rotates through 180 degrees for each movement of the chain 10 corresponding to the length of a pocket. The obliquity of the axis of the cutter member arises from the fact than an appreciable rotation of the cutter is required to sever the web, e.g. 10 degrees. In Fig. 5 the circumferential movement corresponding to 10 degrees of rotation is represented by PQ and QR is the movement of the chain during the period of cutting, the angle between the chain and the axis of the cutter member then being alpha. To compensate for this inclination so that the blades 21 meet the webs at right angles their axes 22 on which they rotate are offset from the axis of the cutter member 14. The mechanism for transferring the severed sweets from the conveyer to a wrapping wheel 36 comprises an eccentric-operated plunger 23 which is caused to move in a path "A", Fig. 4, by a link 27 coupled to a lever 28 fixed to a shaft 29, to which is also fixed an arm 30 carrying a follower 31 coacting with a cam 32, as described in Specification 740,283, [Group XXX]. This action feeds the sweets into pockets 25 in a disc 26 which rotates and brings them above an elevator 35 which, in conjunction with a double top elevator 59, lifts the sweets into the jaws 48 of the wrapping wheel 36. The sweets are prevented from falling out of the pockets 25 by a fixed disc (not shown), a fixed rail 138 and a movable shutter 38 which falls into place when the transfer plunger 23 has withdrawn from the pocket 25 of the feed disc 26. The shutter 38 is pivoted at 39 and is normally held up by a bell crank 43 engaging a tail piece 40 projecting from the shutter, but when the plunger 23 retracts a cam 46 allows the bell crank to turn so that the tail piece is no longer held and a spring 44 acts on another tail piece to cause the shutter to fall into place. Specification 504,576 also is referred to.

Abstract: 442,586. Heating systems; refrigerating. ELECTROLUX, Ltd., Luton, Bedfordshire.-(Platen-Munters Refrigerating System Aktiebolag; 2, Norrmalmstorg, Stockholm) July 7, 1934, No. 19981. [Classes 29 and 64 (ii)] Closed evaporating-condensing fluid systems for heating domestic apparatus, such as a heating cabinet 15 or absorption refrigerating apparatus 20 for a refrigerator 21, from a primary heat source such as a cooking stove 10, are charged with such a limited amount of the medium that it is completely vaporized at excessive temperatures of the primary heat source and does not transmit excessive heat to the secondary apparatus. Preferably, the medium has a critical temperature not more than 10‹ C. above the normal operating temperature of the secondary apparatus. In the case of absorption refrigerating apparatus having a central flue in the generator to adapt it for heating alternatively by electricity, gas or oil or by the heat transfer system, the condenser element 19 of the heat transfer system may be adapted to fit into the flue. The used cooling-air of the refrigerating apparatus may be led through the walls of an associated heating cabinet, in which case the heating cabinet need not be heat insulated. Suitable media for heat transfer to the refrigerating apparatus are pentane, ether, acetone and methyl alcohol.

Title: Improvements relating to vitreous tubular envelopes
IPC: B60C17/00
Filed: 1944-10-19
Abstract: 621,465. Electric incandescent lamps. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 19, 1944, No. 20268. Convention date, Oct. 21, 1943. Drawings to Specification. [Class 39(ii)] [Also in Group XL (a)] A method of rendering a substantially flat vitreous envelope tube, such as for an incandescent lamp, resistant to collapse by unbalanced external atmospheric pressure when the tube is evacuated, consists in chilling the longitudinal tube edges from a temperature above the strainpoint of the material to below that temperature in advance of the cooling of its wide longitudinal walls. It is stated that the longitudinal edges are put in a state of permanent preconpression or bending strain. The heating of the tube above its strainpoint may be merely incidental to drawing out and forming the glass into a flat tube, or may be a subsequent heating for the purpose of flattening an initially round-formed tube, or may be a special heating for the main purpose of imposing strain at the edges. The prechilling of the tube edges in advance of the cooling of its wide walls may be effected by blowing air on the edges, or by heating the wide walls to keep them above the strainpoint while the edges are exposed to the circumambient air and then allowing the wide walls to cool, or by merely lagging the wide walls to retain their heat. The wide walls of the tube may be perfectly flat or slightly convex outwards. As described with reference to a fluorescent discharge lamp, the tube may be flattened substantially throughout its length between round ends, or flattened right out to its very ends. Specification 486,325, (Group XL), is referred to.

Title: Wave-signal transmission lines
IPC: H01P7/02
Filed: 1944-10-26
Abstract: 585,066. High-frequency transmission lines. HAZELTINE CORPORATION. Oct. 26, 1944, No. 20912. Convention date, Jan. 28. [Class 40 (iii)] A folded high-frequency transmission line, whose length may be adjustable, is so dimensioned that coupling between successive folds of its inner conductor is reduced and the line is in consequence electrically long though physically compact. The inner conductor may comprise a loop 14, 15, Fig. 1, forming the inner conductor of a section of coaxial line, the screen 19 forming a common outer conductor for both legs 14, 15 of the loop. Since these legs are not screened from one another, they are subject to mutual coupling which shortens the line electrically, but this effect is reduced by making the width D of the screen, Fig. 2 (cross-section at 2-2, Fig. 1) substantially less than the distance between the legs 14, 15, so that the electric images formed in the screen tend to neutralize the effect of each leg on the other. The nearest distance between the surfaces of the legs must be at least equal to, and preferably twice as great as, the width D, and the side walls of the screen are parallel to the median plane of the loop 14, 15. The external connections are effected through two jacks 24, 24 of the coaxial type. The loop 14, 15 is telescopic and its length is adjusted by means of a rod 21, and in order that the characteristic impedance may be invariable, a movable end wall 16 is mounted integrally with the loop 14, 15 and is connected to the screen 19 through contact fingers 20 or capacitively. Alternatively, the transmission line may comprise a pair of parallel loops enclosed in an outer screen whose sides are parallel to the medium planes of the loops, Fig. 3 (not shown), and in this case each loop is screened by the other loop and one side of the outer screen. The line may be electrically lengthened by providing a solid dielectric between the extensible part of the loop 14, 15 and the screen 19, Figs. 4 ... 8 (not shown), and in order that the characteristic impedance may not thereby be reduced, the distributed inductance is increased by making the extensible part of the loop of flat strip and by suspending finely divided magnetic material in the solid or liquid dielectric. The screen 19 may have an elliptical cross-section.
